Factor XIIIa is used as a marker for fibro-histiocytic proliferations, dermal dendritic cells and to differentiate dermatofibroma from dermatofibrosarcoma. FACTOR XIIIA POSITIVE DERMAL DENDROCYTES IN AMERICAN TEGUMENTARY LEISHMANIASIS CUTANEOUS TISSUE RESPONSE The role of Langerhans cells in the pathogenesis of skin infectious diseases is well studied, however, there are few papers addressing factor XIIIa positive dermal dendrocytes (FXIIIa+DD) involvement in such processes. Conclusion: Factor-XIIIa-positive dendrocytes probably play a role in the regulation of the connective tissue remodeling that may accompany epidermal destruction. Background: Lymphocyte-poor graft-versus-host-reaction (GVHR) and toxic epidermal necrolysis (TEN) share some histological resemblance. Factor XIIIa positive cells in granulomatous lymph node lesions Factor XIIIa positive cells in granulomatous lymph node lesions Cotton, D.W.K.; Stephenson, T.J.; Hird, P.M. 1990-05-01 00:00:00 Sir: In the recent review (Goudie 1989) of Histological Typing of Thyroid Turnours (Hedinger, Williams & Sobin 1988), attention was drawn to the limited discussion and absence of references in this book DOI: 10.1097/00000372-199810000-00022 Corpus ID: 11184222. CD34 and factor XIIIa-positive microvascular dendritic cells and the family of fibrohistiocytic mesenchymal tumors. Plasmacytoid dendritic cells, Factor XIIIa-positive dermal dendrocytes, macrophages and inducible nitric oxide synthase expression in American tegumentary leishmaniasis skin lesions Factor XIIIa Positive Control Slides , Product No. 251S, are available for immunohistochemistry (formalin-fixed, paraffin-embedded sections).

Numerous large, stellate cells in placental villi, decidua, and chorionic membranes also expressed factor XIIIa at 7–9 weeks gestational age, before the onset of fetal hematopoiesis. Immunohistochemical analysis showed that factor XIIIa-positive histiocytic cells were distributed in the area without haemosiderin, but such cells were absent in the area with its deposition. Factor XIII or fibrin stabilizing factor is a zymogen found from the blood of humans and some other animals. It is activated by thrombin to factor XIIIa.

Factor xiiia positive

By dual-labeling immunofluorescence and confocal microscopy, GPIb alpha-positive cells within the dermal interstitium are demonstrated to represent factor XIIIa-positive dermal dendrocytes. In organ cultures of neonatal human foreskin, mast cell degranulation induced by either substance P or compound 48/80 resulted in transiently increased GPIb alpha expression by dermal dendrocytes. Newcomer Supply Factor XIIIa (fibrin stabilizing factor) Control Slides are for the positive immunohistochemical staining of Factor XIIIa, a blood coagulation enzyme that crosslinks fibrin.

They are subsets of mesenchymal cells, cancer-associated macrophages and antigen-presenting cells. Factor XIIIa-positive dendrocytes present at the periphery and inside epithelial neoplasms are an heterogeneous group of cells. They are subsets of mesenchymal cells, cancer-associated macrophages and antigen-presenting cells. Factor XIIIa positive control slides are intended for use as positive controls for immunohistochemical (IHC) staining using an anti-Factor XIIIa antibody.

Numerous large, stellate cells in placental villi, decidua, and chorionic membranes also expressed factor XIIIa at 7-9 weeks gestational age, before the onset of fetal hematopoiesis. Anti- Factor XIIIa has been found to be useful in differentiating between dermatofibroma (90% positive) and desmoplastic malignant melanoma (negative).

320,000); whereas in platelets, only the alpha2 unit exists. Factor XIIIa is a dermal dendrocyte marker and shows variable reaction with these types of tumors (3,4). Factor XIII a-positive DD may be altered in some genetic disorders affecting the connective tissue structure [15,17,20–26]. There is ample evidence that many, if not all, of these disorders are associated with alterations in the tensile properties of the dermis.

CELiac Identification Among Children CELIAC: A

Objective: To study the ultrastructural aspect of boosted dendrocytes in GVHR and TEN. Dendritic, factor XIIIa positive cells were observed in all tissues studied, but were most numerous in skin and mucosal tissues (gastrointestinal tract, bladder). They were also observed associated with epithelial structures in lung and kidney, but were only rarely observed in liver, thyroid, testis and spleen.

Fibrohistiocytic marker; note that peritumoral cells may also exhibit Factor XIIIa staining Also active form of factor XIII, an enzyme of coagulation system that crosslinks fibrin (Wikipedia: Factor XIII [Accessed 2 August 2018]) In this report, by the combination of double immunohistochemical staining and immunoelectron microscopy, we demonstrate that factor-XIIIa-positive cells are distinct from Schwann cells, perineurial cells, endothelial cells, mast cells, and conventional macrophages, but correspond to the fibroblastlike cells in cutaneous neurofibromas. Factor XIIIa is a blood coagulation prototransglutaminase 1, which becomes an activated component of the final stages of the clotting cascade as a result of the interaction with thrombin and Ca 2+.
